1. Provide a complete retrosynthesis and forward synthesis of the target molecule below from the given starting materials. All carbons of the target must be from the given starting materials. You may use any reagents you find necessary. You may include more than one step over a reaction arrow, but please no more than 3 steps at a time. Please show the key intermediates in your synthesis for partial credit. (10 bonus points) For full credit, include a retrosynthetic analysis,...

Problem IV. Synthesis (24 points). These transformations will require multiple steps. Provide the reagents for each step and draw out your proposed synthetic intermediates. Please do not draw curved arrows; this prob- lem is not asking for mechanisms. You do not need to provide solvents for the reactions.

Synthesis 1. The following transformations cannot be performed in one step. Provide a sequence off reactions to convert the "starting material to the "product. Show all the reagents and synthetic intermediates. You can use any additional carbon sources if needed, but you must use the starting material given. .Cl H EAODa mess OH Ha0 HO $7 OH CEC-Me ১৯ ) mcPEA OW PAC OH OH -Br LOH HBr percxida
Using propyne (structure shown) as your only source of carbon atoms, design a synthesis of the target molecule. You may use any organic or inorganic reagents you choose, but all the carbon atoms in the target must have come from propyne originally. Show the product of each step and the reagents needed for each step. Assume you have an unlimited supply of propyne.
